A highway patrol officer on the ground uses a radar gun to measure the speed of a suspect's car to be 60 m/s. a patrol car is traveling at 40 m/s relative to the ground, but is moving in the opposite direction as it approaches the car. assume that the direction in which the suspect is traveling defines the +x direction for everyone. what object should we choose to be the Home Frame for this problem? What object defines the Other Frame? What object is the object whose velocity we want to determine in both frames? Calculate the relative velocity of the suspect's car and the patrol car.
